He sure did. They were on the brink of a 3 peat and went into 2005 with that crap in the secondary. No replacement for Bruschi when he had a stroke.
Then he let Branch, Givens and McGinest go without replacements. They win in 2006 with those players. This is what contributed to the 10 year drought.
You could argue Aqib Talib was better long term than Revis. I was tired of Talib when he got a 2nd straight boo boo in the AFCCG's and he had said Bill didn't want to re-sign him because he was unreliable. He became iron man for sometime and came back to haunt them in 2015.
